OIL-VAPOR BURNER.

SPECIFICATION forming part of Letters Patent No. 738,463, datedSeptember 8, 1903.

Application filed December 18,1902. Serial No. 135,699. (No model.)

1'0 all whom it near/y concern:

Be it known that I, ALBERT J. LINDEMANN,

a citizen of the United States, residing at Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and usefulImprovements in Oil-Vapor Burners,

of which the following is a specification, reference being had to theaccompanying drawings, forming a part thereof.

This invention relates to self-generating oil-vapor burners speciallydesigned for the more volatile hydrocarbons, such as gasolene. Its mainobject is to simplify and'improve the construction and operation of thisclass [5 of burners, and particularly to completely vaporize the oilbefore it reaches the jet-nozzle with the axis of the air-n1ixing tubein assembling the parts of the burner and to avoid as far as practicablethreaded joints in the construction of the burner. 1

It consists in certain novel features of construction and in thearrangement and combinations of parts, as hereinafter particularlydescribed, and pointed out in the claims.

\ In the accompanying drawings like letters designate the same parts inthe several figures.

Figure 1 is a view, partly in side elevation and partly in verticalmedial section, of a burner embodying myimprovements. Fig. 2 is aninverted plan view of the base-plate and a horizontal section on theline 2 2, Fig.1; and Fig. 3 is a similar section on the line 8 3, Fig.1.

a is a substantially circular base plate formed on the upper side with acircular depression in which is loosely fitted the perforated cap b inthe usual or any suitable manner.

c is a vertical air-mixing tube fitted and held in a central flangedopening in the baseplate and projecting upwardly through the same in theusual way.

On one side the plate a is formed with an 45 ear or extension (1, havinga circular hole through it and a recessed seat 6 of angular orirregular'shape in the under side around said hole.

fis a hollow vaporizing-head having a cir- 5o cular threaded portionfitted to pass through and extend upwardly above the hole in said,

base-plate and also having a shoulder below said circular portion fittedin the seat 6. This head is secured in the base-plate above which itprojects, as shown in Fig. 1, by a nut g.

h is a vapor-jet nozzle connected with the headf by an angular pipe orpassage t', which is formed integrally with said nozzle and head. Theposition of the nozzle relative to the baseplate a is thus determined bythe engagement of the shoulder or enlargement of the headf With therecessed seat 6 in said baseplate, and the nozzle is thus brought intoand securely held in exact axial alinement with the air-mixing tube 0when the parts of the burner are assembled as shown in Fig. 1. Thenozzle h is provided, as usual, with a valvej for opening and closingitand for admitting oil int-o a cup on the lower part of the nozzle forheating the burner preparatory to lighting it. The vapor-feed tube t' isalso provided in the usual way with a regulatingvalve Z.

we is a vertically-arranged oil-supply pipe threaded at its upperend inthe lower part of the headfand communicating above the base-plate athrough a passage n in said head with the passage in the pipe 1'.

By this construction and arrangement of the oil and vapor pipes and thevaporizing-head fthe oil supplied through the pipe m is compelled topass into the upper part of the head f, which is exposed directly to theflame of the burner and is highly heated thereby. After the burner hasbeen heated the oil in its passage thereto is thus completely vaporizedbefore it enters the pipe z'. The pipe m is preferably provided with afilter or strainer o, of loose cotton or other suitable material, heldtherein between perforated caps 19, in? sorted in the ends of said pipefor the'purpose of removing any impurities contained in the oil beforeit enters the vaporizing-head.

Except as above explained the operation of the burner is like or similarto that of burners of this class. To start the burner, both the valves70 and Z are opened and oil is allowed to overflow the nozzle it intothe cup 70, in which it is burned till the parts of the burner areheated sufiiciently to vaporize the oil before it issues from saidnozzle.

, by the valve Z entrains air with it upwardly through the mixing-tube 0into the cap I), from the perforations in which the inflammable mixtureof oil-vapor and air issues and burns with a blue flame. The flame fromthe lower row of holes in the cap impinges against the vaporizing-headf, keeping the same hot and completely vaporizing the oil as it issupplied thereto through the pipe m.

Various changes in minor details of construction and arrangement ofparts may be made within the spirit and intended scope of the invention.

I claim 1. In an oil-vapor burner the combination of a base-plateprovided with a vertical airmixing tube and with a perforated cap, aheadextending above said plate and exposed to the flame of the burner, saidhead having a vaporizing chamber or passage also extending above saidplate, and a jet-nozzle arranged below and in alinement with saidmixingtube and connected by a pipe or passage with said head,substantially as described.

2. In an oil-vapor burner the combination of a base-plate having avertical air-mixing tube and an opening on one side of said tube, anexternally threaded and shouldered vaporizing-head fitted in saidopening and secured therein by a nut and a jet-nozzle integrallyconnected with said head by a pipe or passage and held thereby inalinement with the axis of said air-mixing tube, and an oil-supply pipeconnected with said head and com m u nicating with the aforesaid pipe orpassage above said base-plate, substantially as described.

3. In an oil-vapor burner the combination of a base-plate having anair-mixing tube perpendicular thereto and an opening and recessed seatat one side of said tube, a hollow vaporizing-head fitted in saidopening and seat to project above said plate and secured therein by anut threaded on said head, a jetnozzle formed integrally with said headand held thereby in axial alinement with said airmixing tube, and anoil-supply pipe threaded in said head below said plate and communicatingabove said plate with the passage leading to said nozzle, substantiallyas described.

4. In an oil-vapor burner the combination of a base-plate provided witha perforated cap and with a vertical air-mixing tube and having anopening through it on one side of the cap-seat, a hollow vaporizing-headsecured in said plate and projecting above it adjacent to one or moreopeningsin the cap, a jet-nozzle arranged in aliuement with the axis ofsaid air-mixing tube and connected by a passage with said head above thebase-plate and an oil-supply pipe located below said baseplate andconnected above it by a passage with the passage leading to said nozzle,substantially as described.

In witness whereof I hereto affix my signature in presence of twowitnesses.

ALBERT J. LINDEMANN.
